ENCLOSED REFLEX SIGHT FOR FIREARMS, ASSEMBLY, SYSTEM AND METHOD

BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure

This disclosure relates generally in the field of optical sights for firearms.

2. Background Art

A reflex sight is a type of non-magnified (lx) electronic optical sight for firearms that is commercially available as an open reflex sight and as an enclosed reflex sight. An open reflex sight typically has a partly open housing with a single lens in an optical pathway of a user's eye, e.g., a shooter's eye, and an exposed light source on the housing. An enclosed reflex sight has a housing with multiple lenses in an optical pathway of a user's eye, and a light source located within the housing that assists in protecting the light source against environmental influences such as dirt and moisture.

As understood by the skilled artisan, a housing of an enclosed reflex sight provides a field of view including a projected reticle to assist in aiming a corresponding firearm. Some enclosed reflex sights include windage and elevation adjustment mechanisms within the housing below the field of view. Other enclosed reflex sights house a light source in a pivot tube that allows the windage and elevation adjustment mechanisms to be located at the top of the housing or on the side in line with the field of view. In both configurations, the windage and elevation adjustment mechanisms are operationally configured to assist a user in matching a projectile impact for a firearm to an aiming point of the closed reflex sight.

In typical operation, an enclosed reflex sight is secured to an upper mounting surface of a firearm via a mounting interface at a position forward of a protruding rear sight, i.e., a rear iron sight, of the firearm. In one known implementation, an upper mounting surface may include an upper surface 555 of a firearm 550 whereby a mounting interface 525 is secured directly to the upper surface 555 via one or more threaded fasteners 556 forward of a rear sight 530 (see the mounting interface 525 releasably secured to an upper surface 555 of a pistol slide 575 in FIG. 1). As shown in FIG. 2, in another known implementation an upper mounting surface 557 of a particular size and shape may be formed along an upper surface 555 of a firearm 550 for receiving a mounting interface 525 (see FIGS. 2 and 3). In this implementation, the upper mounting surface 557 commonly includes a bottom surface 570, a forward or front wall surface 571 and a rearward or back wall surface 572 located forward of a rear sight 530 operationally configured as a mounting surface envelope for receiving a mounting interface 525 for securing an enclosed reflex sight at a position forward of a rear sight 530 as shown in FIG. 3.

In each of the implementations described above, the entire enclosed reflex sight 500 is located at a point between a rear end surface 538 and a front end surface 539 of the firearm 550 on top of the mounting interface 525 forward the rear sight 530 whereby the mounting interface 525 spaces the enclosed reflex sight apart from the upper mounting surface of the firearm. Because the elevation adjustment mechanism of a known enclosed reflex sight 500 as shown in FIG. 3 operates in a vertical direction, the housing must include enough space to accommodate the elevation adjustment mechanism. Unfortunately, an enlarged housing raises the location of an optical center 505 of a clear aperture or usable field of view of the enclosed reflex sight 500 in relation to both the upper mounting surface of the firearm 550 (see the bottom surface 570 of the upper mounting surface 557 in FIG. 3) and the top of the original equipment (“OE”) standard height iron sights for a particular firearm thereby preventing the rear and front sights from being used for purposes of co-witnessing with the enclosed reflex sight 500 (see the sighting line 540 of the standard height rear sight 530 and front sight 531 and distance 541 in FIG. 3; also see the no-witness position between the standard height iron sights 530, 531 and the reticle 535 of the enclosed reflex sight 500 in FIG. 4). To achieve co-witnessing, the standard height iron sights 530, 531 must be replaced with taller aftermarket rear and front sights 532 and 533 as shown in FIG. 5.

In consideration of the above described enclosed reflex sight 500 design, another enclosed reflex sight 590 known in the art houses electronics and adjustment mechanisms in a rear section 591 that extends beyond the upper surface 555 of a firearm 550 behind a rear end surface 538 of a pistol slide 575 as shown in the simplified illustrations of FIGS. 6 and 7. However, as shown, an enclosed reflex sight 590 of this embodiment may require adjustment in design to accommodate pistol slide 575 geometry of a particular firearm 550. In addition, the corresponding firearm 550 does not employ a rear sight.

An enclosed reflex sight that overcomes the above shortcomings while also being operable with a plurality of firearm mounting footprints is desired.

As previously discussed above, an inner surface 97 of the bottom plate 76 acts as a floor of the compartment 70. As such, the bottom plate 76 is operationally configured as a support surface for the adjustment assembly 100 and may be considered part of the adjustment assembly 100 for purposes of this disclosure.

Looking at FIG. 26, the adjustment assembly 100 includes an elevation ramp member 102 and an emitter seat 104 having a bottom facing ramp surface 101 operationally configured to ride on a corresponding ramp surface 103 of the elevation ramp member 102. As shown, the emitter seat 104 also includes a forward ledge type support surface 105 (“forward ledge 105”) for holding an emitter assembly carrier 29, which acts as a support for holding the emitter assembly 25.

In addition to the emitter assembly carrier 29, windage adjustment of the emitter assembly 25 is accomplished via windage adjustment components including (1) a threaded windage drive screw 110, (2) a threaded windage adjustment key 112 for threadedly mating with the windage drive screw 110, (3) a threaded windage retaining ring 114 for threadedly mating with the windage adjustment key 112, (4) an O-ring seal 116 attachable to the windage adjustment key 112 and (5) a windage wedge member 118 operationally configured to bias the emitter assembly carrier 29 and the windage drive screw 110 as described below.

In this embodiment, the emitter assembly carrier 29 includes a central support member 108 with opposing abutment members, e.g., a first abutment member 106 with a first wedge contact face 128 operationally configured to communicate with a wedge contact face 111 of a head 117 of the windage drive screw 110 and an opposing second abutment member 107 with a second wedge contact face 129 operationally configured to communicate with a wedge contact face 119 of the windage wedge member 118. As shown, the central support member 108 includes a front planar face member 115 for receiving an emitter assembly 25 in abutment thereto via one or more adhesives. Suitably, the first abutment member 106 and the second abutment member 107 are spaced apart a distance effective to hold the forward ledge 105 in abutment there between preventing unwanted lateral movement of the emitter seat 104 when the emitter seat 104 is biased by the elevation ramp member 102 as described below. As such, in one embodiment the emitter assembly carrier 29 may be considered part of the windage adjustment mechanism of the adjustment assembly 100.

Still referring to FIG. 26, the adjustment assembly 100 comprises a plurality of biasing springs and corresponding plungers that apply tension to the inner surface of the compartment 70 to assist in maintaining the windage adjustment components and the elevation adjustment components in desired positions within the compartment 70 during operation of the adjustment assembly 100. For example, the first body member 128 of the emitter assembly carrier 29 includes a vertical hole 130 for receiving a biasing spring 131 and a plunger 132 therein and the second body member 107 includes a vertical hole 134 for receiving a biasing spring 135 and a plunger 136 therein to bias the emitter assembly carrier 29 apart from the ceiling 75 of the compartment 70. Likewise, the emitter seat 104 includes one or more vertical holes 138 and 139, each vertical hole being operationally configured to receive a biasing spring and a plunger therein to bias the emitter seat 104 apart from the ceiling 75 (see biasing springs 140, 141 and plungers 142, 143). In other words, when the adjustment assembly 100 is secured within the compartment 70 the emitter assembly carrier 29 and the emitter seat 104 are biased toward the bottom plate 76. In one embodiment, the inner surfaces 85 and 86 and the ceiling 75 may include cavities (not shown) for holding the distal ends of the corresponding plungers.

In this embodiment, the elevation ramp member 102 includes a raised body member 145 comprising a horizontal hole 146 for receiving a biasing spring 147 and a plunger 148 therein to bias the elevation ramp member 102 apart from the inner surface 85 of the left sidewall 71. The windage wedge member 118 also includes one or more horizontal holes 150 and 151 (see FIG. 29) for receiving a biasing spring and plunger therein to bias the windage wedge member 118 apart from the inner surface 86 of the right sidewall 73 (see biasing springs 152, 153 and plungers 154, 155).

Referring again to FIGS. 17 and 18, the adjustment assembly 100 is further secured to the compartment 70 by way of the windage adjustment key 112 and the elevation adjustment key 124 which are each communicated with apertures in the housing 12. In particular, the left sidewall 71 includes an aperture 158 with an inner cylindrical perimeter surface for mating with a circular head 113 of the windage adjustment key 112 and the right sidewall 73 includes an aperture 159 with an inner cylindrical perimeter surface for mating with a circular head 125 of the elevation adjustment key 124. In particular, the windage adjustment key 112 includes a round detent 161 and a corresponding biasing spring 162 disposed radially in a hole 165 of the circular head 113 and the elevation adjustment key 124 includes a round detent 166 and a corresponding biasing spring 167 disposed radially in a hole 168 of the circular head 125 for mating with raised splines disposed 360.0 degrees along the inner perimeter surface of each of the apertures 158 and 159 (see the raised splines 160 and 170 in FIGS. 17 and 18). In operation, the detents 161 and 166 operate as ball plungers that are biased between the raised teeth 160 and 170 under spring tension necessary to hold the windage adjustment key 112 and the elevation adjustment key 124 in a fixed position until manually turned to disengage the detents 161 and 166 when adjusting the windage and/or elevation. In addition, the configuration of the detents 161, 166 and the raised teeth 160, 170 produces a clicking sound and/or a clicking feel to a user when turning the windage adjustment key 112 and the elevation adjustment key 124.

In one embodiment, the circular heads 113 and 125 of the windage adjustment key 112 and the elevation adjustment key 124 may each comprise a drive 172, 173 to assist in manually turning the adjustment keys 112 and 124, e.g., using a slotted flat blade screw driver or an adjustment tool as known in the art of optical sights. In addition, a shank of each of the adjustment keys 112 and 124 may include a concentric groove adjacent the circular heads 112 and 125 for holding an O-ring seal 116, 126 to form a seal along the inner surfaces 177, 178 of the apertures 158 and 159 to protect against environmental influences such as dirt and moisture from entering the housing 12 through the apertures 158 and 159 (see grooves 175 and 176 in FIG. 26).

In one embodiment, the windage retaining ring 114 is permanently fixed to an outer threaded surface 156 of the adjustment key 112 and the elevation retaining ring 122 is permanently fixed to an outer threaded surface 137 of the adjustment key 124 whereby the windage retaining ring 114 and the elevation retaining ring 122 are operationally configured to further secure the adjustment assembly 100 to the housing 12 by similarly acting as stop type members preventing the windage adjustment key 112 and the elevation adjustment key 124 from exiting out from the apertures 158, 159. For example, referring to the elevation adjustment key 124 as shown in FIG. 27, the inner surface 178 of the aperture 159 includes a concentric flange 169 operationally configured as an abutment surface for the elevation retaining ring 122 whereby the concentric flange 169 and the elevation retaining ring 122 operate collectively as a stop for catching the head 174 of the elevation drive screw 120 preventing the elevation adjustment key 124 from being directed out from the housing 12 through the aperture 159. The elevation retaining ring 122 and the flange 169 are also operationally configured to maintain the outer face 133 of the circular head 125 of the elevation adjustment key 124 flush with the adjacent outer surface of the housing 12 (see FIG. 21). A similar flange in the inner surface 177 of aperture 158 and the windage retaining ring 114 operate as described above to prevent the head 117 of the windage drive screw 110 from being directed out from the housing 12 through the aperture 158.

To minimize the overall size of the enclosed reflex sight 11, the housing 12 materials including the bottom plate 76 and adjustment assembly 100 components are suitably configured in as small a package allowable for desired functioning of the enclosed reflex sight 11 without realizing structural failure of one or more of the housing 12, bottom plate 76 and adjustment assembly 100 components. As an example, the perimeter of the bottom plate 76 and the perimeter of the opening of the compartment 70 may include corresponding indexing features 181, 182 and 183, 184 (see FIGS. 30 and 31) in order to provide added material thickness to the bottom plate 76 and the bottom surface 98 of the compartment 70 at an abutment 185 between the bottom plate 76 and the bottom surface 98 for providing structural strength to the lower most part of the flange in each of the apertures 158 and 159 (see FIG. 27).

To adjust the emitter assembly 25 vertically up and down, the elevation adjustment key 124, which comprises a shaft having (1) an inner threaded surface 127 in threaded communication with an outer threaded surface 121 of a shaft of the elevation drive screw 120 and (2) an outer threaded surface 137 in threaded communication with an inner threaded surface 144 of the elevation retaining ring 122 may be turned clockwise and counter-clockwise thereby acting on the outer threaded surface 121 to direct the elevation drive screw 120 in a linear direction. For example, to direct the emitter assembly 25 linearly in an upward direction (see directional arrow A1 in FIG. 28), the elevation adjustment key 124 may be turned counter-clockwise directing the head 174 of the elevation drive screw 120 linearly toward the inner surface 85 of the left sidewall 71 against a right side vertical surface 109 of the elevation ramp member 102 (see directional arrow A2 in FIG. 28) causing the ramp surface 103 of the elevation ramp member 102 to act on the ramp surface 101 of the emitter seat 104 pushing the emitter seat 104 upward (see directional arrow A1) via a sliding coupling between the ramp surface 101 and the ramp surface 103. As the emitter seat 104 is directed in an upward direction, the emitter assembly carrier 29 and the emitter assembly 25 secured thereto are simultaneously directed in an upward direction a distance equal to the distance traveled by the emitter seat 104. Suitably, the detent 166 and biasing spring 167 are operationally configured to engage the raised splines 170 to assist in fixing the location of the emitter assembly 25, biasing springs 152, 153 and plungers 154, 155 during use of the enclosed reflex sight 11.

To direct the emitter assembly 25 in a downward direction (see directional arrow A3 in FIG. 28), the elevation adjustment key 124 may be turned clockwise as desired to direct the elevation drive screw 120 linearly toward the inner surface 86 of the right sidewall 73 whereby the elevation ramp member 102 is simultaneously directed linearly toward the inner surface 86 of the right sidewall 73 via a biasing force of the biasing spring 147 mated to the elevation drive screw 120 allowing the emitter seat 104 to slide down the ramp surface 103 to a desired elevation of the emitter assembly 25 along the ramp surface 103. Accordingly, rotational movement of the elevation adjustment key 124 is converted into linear movement of the emitter assembly 25.

To adjust the emitter assembly 25 horizontally left and right, the windage adjustment key 112, which comprises a shaft having (1) an inner threaded surface (not shown) similar as inner threaded surface 127 in threaded communication with an outer threaded surface 149 of a shaft of the windage drive screw 110 and (2) an outer threaded surface 156 in threaded communication with an inner threaded surface 171 of the windage retaining ring 114 may be turned clockwise and counter-clockwise thereby acting on the outer threaded surface 149 to direct the windage drive screw 110 in a linear direction. For example, to direct the emitter assembly 25 linearly toward the inner surface 86 of the right sidewall 73 (see directional arrow A5 in FIG. 29), the windage adjustment key 112 may be turned counter-clockwise directing the wedge contact face 111 of the head 117 of the windage drive screw 110 linearly against the first wedge contact face 128 of the first abutment member 106 of the emitter assembly carrier 29 to direct the emitter assembly carrier 29 toward the inner surface 86 of the right sidewall 73 according to (1) a sliding coupling between the wedge contact face 111 of the head 117 of the windage drive screw 110 and the first wedge contact face 128 of the first abutment member 106 and (2) a sliding coupling between the second wedge face 129 of the second abutment member 107 and the wedge face 119 of the windage wedge member 118, which further directs each of the emitter assembly carrier 29 and the windage wedge member 118 linearly toward the inner surface 86 of the right sidewall 73.

To direct the emitter assembly 25 toward the inner surface 85 of the left sidewall 71 (see directional arrow A6 in FIG. 29), the windage adjustment key 112 may be turned clockwise as desired to direct the windage drive screw 110 linearly toward the inner surface 85 of the left sidewall 71, whereby a biasing force of the biasing springs 152, 153 of the windage wedge member 118 directs the wedge face 119 of the windage wedge member 118 against the second wedge face 129 of the second abutment member 107, which further directs the first wedge face 128 of the first abutment member 106 against the wedge face 111 of the head 117 of the windage drive screw 110 in a sliding action until the emitter assembly 25 realizes a desired position within the compartment 70. Accordingly, rotational movement of the windage adjustment key 112 is converted into linear movement of the emitter assembly 25.

As stated above a mounting interface 14 of the assembly 10 is positioned forward of the adjustment assembly 100 housed in the compartment 70 when the mounting interface 14 is assembled to the enclosed reflex sight 11. As such, the attachment points on the enclosed reflex sight 11 for receiving a mounting interface 14 of this disclosure are also positioned forward of the adjustment assembly 100 of the enclosed reflex sight 11.
